Application May 3. 1941, Serial No. 391,752

4Claims.

Our invention relates to building construction and more particularly to a new and novel manner of' buildi g a house with prefabricated sections ready forv installation, each section being locked to the next adjoining section by a locking strip, nailed and glued in such a manner as to lock the. sections into a rigid and solid wall.

A. further object is to provide a new building construction joint made between sections of a prefabricated house, the joint being made to permit the usual warpage of the two by four and one by. four joists without enacting the joint after it has been secured together.

A still further object is to provide a building joint for Joining prefabricated sections of a building together which Joint is made by inserting locking strips in suitable channels, the strips to be nailed to the joists but nailed and glued to the plywood inner and outer wall surfaces permitting expansion between the joists and walls but preventing any expansion between the abutting wallboard or plywood sections.

This application relates to a continuation in part of my former patent application filed in the Patent Oilice as a co-pending application Serial No. 362,024, under date of Oct. 21, 1940.

These objects I accomplish with the device illustrated in the' accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specication forming a part of this application and pointed out in the ap-v pended claims.

sheets 5 and t are spaced by a re stop horizonltal ioist Il medially of the joists 9 and III. The

vertical ioists 'l and 8 are narrower than the horizontal joists 8 and l0 and the re stop joist II, and when the framework is made and the panel sheets 5 and 8 secured to the horizontal jolsts there is a s'pace I6 remaining between one side of the panel boards and the vertical joists and a like space I6 on the other side. Into these spaces plywood locking and binding strips I1 and It are placed and secured. Strips i1 and I8 are set in the spaces I5 and I6 of the panel A with glue being rst spread over the side of the strips adjacent the panel board surface and the glue is forced in or wiped in by first spreading it thickly on the side of the strip which is abutting the inside of the -panel surface only, and not on that side which will meet the vertical joists. When the glue has .been forced in and the strips are in place they are nailed in place with the nails passing through the strips into the Joists. The sliding of the strip into the space wipes the glue fror'n the strip onto the inner side of the I panels 5 and 6 and when the glue is'- dry the.

- In the drawing in winch I have shown my de- I vice Figure 1 is a perspective view ot two of the wall panels set together parts cut away to show the joint between the panels.

Figure 2 is an exploded sectional view of the joint as the two abutting edges would appear when ready for setting them together to form the wall.

Figure 3 is a sectional view of the nished joint dotted lines indicating the nails used in the joint.

Figure 4 is an end elevation of the panel in position in a wall. y

In the drawing, we have shown our panel sections as A and B and they consist of outer panel boards or sheets 5 and inner boards or sheets i spaced apart by a framework consisting of horizontal joists 9 and Ill and vertical joists 1 and 8 with the Joists 1 and 8 set in at each end a short distance as shown at Il in Figure 2, and which when the joints are made between abutting sections leaves a space I2 for expansion and contraction and for warpage of the ioists. The

combination of glue and nails securely locks the strip in place. v

When building the side Wall of the house, each panel carries the securing strips along one side of the joist. When setting the two panels together glue is wiped onto the outside face a of the strips I1 and I8 and the two panels are pressed together and this action wipes the glue onto the inner surface of the panels 5 and 6 with the strips sliding into the spaces I5 and I6, and as sufficient glue is used the glue is forced out between the abutting ends of the two joists and forms a bead between each panel which is later wiped o. This provides a glue joint between the abutting vertical edges of the panels 5 and 8 and the glue joint between the inner surfaces of the panels 5 and 6 and the outer surface of the strips I1 and I8. The only hold that the Joists have with the outer panels 5 and 6 and with the strips I'I and I8 is by the nails which are driven through the panels and strips into the joists.

Having thus described our invention we desire to secure by Letters Patent and claim:

1. A construction joint comprsing panels made.

each sae of the :01ers ricca swt by the verucal joists, one of the strips overlapping and secured to adjacent edges of a pair of panels, and

the other strip overlapping and secured to ad jacent edges of the other panels.

board and joist'oi one panel and tting into a like space in the next adjacent panel on one out-4 side face of the joist and a like strip on the inside face of the joist,said binding strips glued only on the side adjacent the panel board; and nails driven through the panel, lstrip and into the joist providing a yielding contact between `the Joist and binding strips.

3. A new joint for use where two ends oi prefabricated panel members are joined in making a wall, comprising vertical joists set in the panels spaced inwardly from the vertical edge of the inner and outer boards of the panels with space desde between the two edges of 'each ioist and each side board: binding strips oi' plywood ntting into the spaces left along each edge of each joist overlapping the juncture line of theoutside and inside boards,with the strips glued to the boards but not glued to the joists; and nails securing the boards. binding strips and ioists into a fixed joint with yieldability between the joists and binding strips. y

4. A wallboard structure for building purposes comprising panels made of inner and outer plywood boards spaced apart by'vertical and borizontal joists with the vertical joists narrower,

than the horizontal joists,A leaving a space therein between the board and the vertical joists, and with the vertical joists set inwardly spacedirom the edge of the boards and binding strips spaced apart by the vertical joists, one ot the strips overlapping and secured to adjacent edges of a pair of boards and the other strip overlapping and secured to adjacent edges o! the other boards.
